SPADE-HANDLE.

SPECIFICATION forming part of Letters Patent No. 744,756, dated NovemberApplication filed July 21, 1903. Serial No- 166.4=60. (No model.)

To all whom it may concern.-

Be it known that I, OLE SVENNUNGSEN HAUKVIK, a subject of the King ofSweden and Norway, residing at Sande, in the Provii nce of Thelemarken,Kingdom of Norway, have invented a new and useful Improvement .inSpade-Handles, of which the following is a specification.

. This invention relates to fo ding spades;

f I0 and it hasfor its object to'p'rovid'e a device of this class whichshall possess superior advantages in point of simplicity, durability,

and general efficiency.

My improved spade, while not limited to 5 any particular use, may bestated as being 7- constructed especially for military purposes,

in compact shape and which when thus folded may be readily strapped ontoa knapsack or otherwise carried by the-soldier, the said 1 tool beinguseful for a variety of purposes, among which that of throwing upfortifica tions of course is preeminent. It may, however, additionallybe used as a shield and f also, incidentally, as a gun-rest, for whichlatter purpose it is especially adapted. My 7 improved spade, however,will also be found extremely useful for prospectors and others whosecarrying capacity is limited and to 3o whom it is an object'of greatimportance to have a digging-tool which may be carried in small compassand whi h while lir ited as to the size thereof, shall Lexpos'sessed ofsuflicient strength and durability to enable it to i be advantageouslyused.

With these and other ends in view my i11 vention consists in theimproved construction, arrangement, and combination of partsconstituting the members of my said improved 4o spade, which will behereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front view showing the spadeready for use.

Fig. 2 is a side view showing the spade unfolded, but with theconnecting-sleeve raised,

so as to expose the joint. Fig. 3 is a side elevation showing the spadefolded. Fig. 4

v is a side View showing the spade partially un- .59 folded in aposition to serve as a gun-rest.

comprising a tool which may be readily folded g r'o6ve'11,formed in theadjacent ends of the Corresponding parts in the several figures areindicated by similar numerals of referonce.

The shaft of my improved spade is composed of an upper and a lowersection, (designated, respectively, 1 and 2.) The upper section isprovided with a handle 3, and the lower section is pointed, so as toengage a socket 4 in the blade 5, with which the said lowerhandle-section is permanently connected. The upper edge of the blade hasa forwardly-extending flange 6, forming a tread upon which the foot ofthe operator may be placed. The shaft-sections l and 2 are provided attheir meeting ends with notches or recesses for the reception of aconnectinglink 7, which is pivotally connected with the notched ends ofthe shaft-sections 1 and 2 by means of pivotal pins 8, which may beremovable, if desired, so as to enable the sections to be disconnectedfor cleaning or other purposes. The shaft-sections are cylindrical inshape, and upon the upper shaft-section is slidinglymounted a sleevei),having an iu teriorly-disposed pin 10, adapted to engage ashaft-sections, said groove being provided at its lower end with alateral extension 12.

It will thus be seen that when the shaftsections land 2 are extended, asin Fig. 2 of p the drawings, the sleeve 9 may bemoved downwardly untilthe pin 10 engages the lateral extension 12 of the groove 11, when thesaid sleevc may be given a short axial twist, whereby th'e'pin' '10shall becaused to enter 8; the lateral extension 12 of groove 11, thussecuring the shaft-sections in an extended position in alinement witheach other, and thus arranging the spade in position for use. The lowershaft-section islprovided with a circumferential collar 13, which limitsthe downward movement of the sleeve 9, so that there shall be no straineither upon the pin 10 or upon the lateral extension 12 of the groove inwhich said pin rides when the sleeve is 95 moved downwardly. The uppereudof the upper shaft-section, bearing the handle 3, is slightly bent ina rearward direction, while the lower end of the lower shaft-section,engaging the socketin the blade, is slightly bent mo in a forwarddirection, as will be clearlv seen in Fig. 2 of the drawings. Lia'simparting to the spade when extended for use a sigmoidal shape, which,as is well known, permits the 5 tool'to be more efficiently wielded. Itspeculiar shape also enables the handle end of the device to fit neatlywithin the blade 5 when the device is folded, as seen in Fig. 3, thuspermitting the device to be compactly folded in a convenient shapeeither for storage or for transportation.

When the members of the spade are halfway extended, as seen in Fig. 4,the device may be readily supported upon the ground, the joint-piece 7being supported in a level position by the adjacent ends of the shaft-.sections, which in this case protrude slightly above the dge of saidjoint-section, as shown at 14. When the device is placed in this po- 20sition, it afiords an excellent gun-rest, as will be readily understood.

It is obvious that the ends of the jointpiece and the abutting ends ofthe shaft-sections will be slightly rounded, as shown, respectively, indotted lines a If :t; Fig. 4 and in full lines at 16 in Fig. 2, in orderto enable the folded.

" The operation of this invention will be readily understood from theforegoing description, taken in connection with the drawings heretoannexed.

The construction of the device is extremely shaft members to beconveniently simple and enables it to be manufactured at a moderateexpense. 1

The spade is capable of being successfully used for any of the purposesfor which a spade is ordinarily employed, while it has additionalqualities not possessed by tools. of this kind as usually constructed.

Having thus described my invention, I claim 1. In a folding spade, anupper and a lower shaft-section provided respectively with a handle andwith a blade, said shaft-sections being provided with notches at theiradjoining ends, a link pivotally mounted in said. notches, an angulargroove in the adjoining ends of the shaft-sections, a sleeve slidablymounted upon the upper shaft-section and having a pin engaging saidangular groove, and a collar upon the'lower shaft-section1i miting thedownward movement of said sleeve.

2. In a folding spade, an upper and a lower shaft-section, a link-jointhingedly connecting said shaft-sections, said upper shaft-section havinga rearwardly-bent handle portion and said lower shaft-section having aforwardly-bent blade portion.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature int-he presence of two witnesses.
